WIRE-SUPPORT.

Sp eeification ofLetters Patent.

Patented May 1 1, 1909.

Application filed July 14, 1908. Serial No. 443,524.

To all whom it may concern:

Be it known that I, THEOPHILUS P. CHAND- LER, a citizen of the UnitedStates, and resident of the city and county of Philadelphia, State ofPennsylvania, have invented an Im rovement in Tire-Supports, of whichthe f0 owing is a specification.

My invention has reference to electric and other wire supports andconsists of certain im rovements which are fully set forth in the folowing specification and shown in the accompanying drawings which form apart thereof.

The object of my invention is to provide a simple and efiioient devicefor supporting electric and other wires, more particularly for use inconnection with electric railways, which may be attached to the wire ina positive manner so as to grip or hold it firmly and without thenecessity of brazing, soldering or other permanent means of union.

My object is also to provide a construction of suspended wire supportwhich is adapted for supporting the wires from above, below orlaterally; and my invention is more particularly directed to theimmediate means by which the wire is supported, rather than theparticular specific use to which it may be applied when employed incommercial use.

The invention is an improvement upon the class of suspension device setout in Letters Patent No. 779,640 dated. January 10, 1905, and whileembodying the great advantages of the construction therein set out alsocombine with them additional features of construction which securegreater strength and more perfect construction.

My invention consists in a support for an electric or other wirecomprising two clam ing body parts united in the direction of t e lengthof the wire, said arts being provided with oppositely grooved portionsfor inclosing the sides of the wire and also with interlocking portionsfor reventing the spreading apart of the two 0 amping body parts andcombined with detachable means for uniting the two parts in theirinterlocking engagement.

My invention further consists in the said wire support above specifiedwhen the opposite ends of the respective clamping parts are formed withadditional grooved portion oppositely directed to the grooved body partsand an oblique entrance between the two said grooved portions of each ofthe clamping parts, whereby the said parts may be first placed obliquelyover the wire and the oppositely directed grooves of each clampingportion made to grip the wire from opposite sides by bringing them intoalinement with the wire, so that not only is the wire gripped betweenthe two clamping parts but it is also gripped between the oppositelydirected grooved portions on each of the clamping parts.

My invention also comprehends details of construction which, togetherwith the features above s ecified will be better understood by re erenceto the drawings, in

which?- Figure 1 is a side elevation of a conductor support embodying myinvention; Fig. 2 is a plan view of the same; Fig. 3 is an inverted viewof the same; Fig. 4 is a cross section of thesame; Fig. 5 is a Viewsimilar to Fig. 3 during the application of the supporting parts; Fig. 6is an inverted view showing how the clamping parts are applied; Figs. 7and 8 are end views showing my invention applied to conductors ofdifferent cross section; Fig. 9 is an elevation of a modification of myinvention when the conductor is supported from below Fig. 10 is a planview of the same, and Fig. 1 1 is'a perspective view of anothermodification of my invention.

A and B are two parts between which electric conductor F is gripped.These two parts are of similar construction and when placed intoengaging position they interlock with each other both vertically andlaterally and firmly hold the conductor without the necessity ofsoldering or brazing. These parts A and B are of considerable lengthwhere they engage the conductor and also have contracted necks, whichwhen brought together form a screw threaded hub C over which thescrewthreaded sleeve D is placed and by which the parts A and B arelocked together. This hub C may also have an in ternal screwthreadedhole for reception of a bolt or screw L by which the suspending devicemaybe attached to a support. InFig. 1 this screw L is held in theinsulator N, such as attached to cross wires in electric railways. InFig. 9 the bolt L is employed as the means of clamping the conductorsupport A B upon an arm N of any permanent fixture such as a cross armor bracket of a pole. The parts A and B have their opposing lower partsinternally grooved as at E to receive and clamp the conductor F betweenthem. The opposite ends of the parts A B are respectively provided withparts A and B whicharealso grooved andfitted upon the facespftheconductor F opposite to those gripped by the grooves of thecorresponding body-parts A and B. As these end portions A B extencL toboth sides ofthe conductor the;grooved part E on one side is cut away asat K and the grooved parts A and B are cut away as at K so as to form. awide throat J for rec-cp tion of the conductor F to eachof'the parts Aand B.

"To apply the parts A and B, they-are-first placed. diagonally acrossthe con ductor -Fvas shown in Fig. 6, then-pressed uporrthe-conductorand-subsequently turned into alinement therewith as shown in Fig. 5,;and

ultimately forced tightly against the conductor and pushed togetherendwiseuntil they engage as in igs. '1, 2 and 3. In this condition, theparts A and 'B -willdirectly clamp grooved parts'in the sametransverse-ahnethe conductor F between their ment, and the end parts Aand B will clamp the-conductor fro n opposite sides-and-alsorespectively in opposite directions to pthe main body-parts A B. Inother words, the parts A and A grip the conductor upon opposite sides;and likewise, the parts B B grip the conductor upon opposlte -sides.From this, it will be seen'that each. of the two parts AB ofthe-supportwill individually sustain the conductorand thatbothof the said partstogether grip the conductor-1n the same transverse plane.

To lock-the two parts A B together adj acent to the conductor, I provideeach of the said parts witha vertical tongue H and-a longitudinal tonguelat one end and with corresponding vertical undercut portions H andreeessesl on the other end, whereby the tongues of each of the saidparts AB will 'fit into the undercut portion andrecesses of-the otherofsaid'parts. The verticaltongues- H and undercutsH interlock the-partsA B- to- ;gether in a horizontal plane and'the tongues I and recesses Iinterlock the-parts A 'B-together both vertically and laterally. It/isevident that either the par-ts H H or the parts I I may be omitted ifdesired; and more broadly considering -my invention, both of said setsof parts H'Hand l-lmay It is also evident that ends, they may beinterlocked at oneend only, as preferred.

In Figs. 1 1306 inclusive I -have shown -n1y invention adapted as ahanger suclras may be used 111 'electrlc' railways, whereas I mF- -gs.

"the parts A-Bmay extend from-the conduc- -,,t0r inanydirection desired.

InFigs. 7 and 8, I have shown the support -;having the groovedportions Eshaped to engage a grooved form of conductor. While it isrrnostdesirable to have the surface of the JLOIldllCtOl F exposed continuouslyalong its oconitact surface, this is not essential as the parts A B maybe extended so as to envelop to a greater or'less extent the conductor.While my invention is especially useful as a supporting device forsuspended electric wires-01* conductors and-has been more" fullydescribed 'inconnection with such use, I do -not restrict myselfto-any-use-as the-supporting device may be used for wires or rods:adapted for ,any purpose. Wl hen con structed as in=Figs.-9,*1-0'and1-1it is especially well adapted for use of'the wire orrod 1as a-raiil or" trackway as in :tel-phersystems and may or not, asdesired, also conduct electricenergy.

"In Fig. '11 the body parts Axand B- are flanged and rest directly uponthe cross arms or ties to which theyarebolted orspiked. l have used theterm "conductor in abroad :senseirrespective:of whether it is intendedfor conveying current or not and hence do not Wish to-be lim-i-ted'inanymanner-to specifie-app'lications of my invention.

t have'shown my invention in the form in which it is excellently adaptedfor comniercial use butl do. not'limit myself to the details as these inay be modified-without departing-fromthe spirit of the invention.
